Must GET/POST Parameters Have Values? (And What is the Syntax for GET, If NOT)

[David T. Ashley]

Are GET and POST parameters required to have values, i.e. are either of
these legal?

http://www.mydomain.com/index.php?this&that

http://www.mydomain.com/index.php?this=&that=

In my application, I have a GET/POST parameter that is significant just by
its presence (it doesn't need a value), and rather than say this=1&that=1 I
was wondering if it is legal to specify them without values.

Thanks, Dave.

yes thats ok, but they need an equals sign at the end still like in
your second example, i havent tried it without, also
empty($_GET['this']) this is fine if you simply want to see if it
doesnt have another value, i use stuff like this for links to member
logins, that way they can be returned back to the same page after a
successful login and ensure everything was there that was before.

I've used like your first example (no equals signs) with no problems
many times. All one must do to see if it is there is:

isset($_GET['this'])

I use this to get different pages from the same php script
